#2I find this extremely fascinating, I've never put any efforts into thinking how this is flying - just because it felt so natural and obvious. A great example of that the obvious can hide greater details we still haven't uncovered.

#3That was a lovely little diversion! There’s a brief 1 minute clip in the article that’s worth watching.
I do have one question though, how is the air flowing up through? It the seed not falling for that to happen?

"Researchers thought that an unattached vortex would be too unstable to persist in nature."

#6Amazing that: (1) the mechanism involves a detached vortex; and (b) that it's taken millennia to understand what makes dandelion seeds fly.

Well, obviously not literally impossible, more like incredible. They float away because they form an unattached air vortex above themselves, and it sucks them up. Flight without work.

#8> Those structures act like the wings of a bird or aeroplane, generating pressure differences above and below the wing to fly.
I thought we had settled this, airplane wings work by deflecting air downward, not by the Bernoulli effect, right?

"Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize."

#10Something something "Bumblebees shouldn't be able to fly" something something.
How is it we are shocked to find out we are sometimes wrong and not shocked that sometimes we get it right?
My critique by the way is the headline, not the actual research. The headline is clickbait IMO, and just as I suppose some don't like my comment (not well thought out, emotional, etc.), the headline is the same.
E.g., consider, "Curious unexpected aerodynamic principles of dandelion seeds lead scientists to new areas of discovery"
